RMH provided mechanical and electrical engineering services for the LEED Gold-certified CAB Barracks Complex at Fort Carson, Colorado—a $94.9 million design-build project supporting the 13th Combat Aviation Brigade. From the outset, the team prioritized energy efficiency, livability, and cost-effective delivery to achieve net-zero energy performance.

Spanning 370,156 square feet, the complex includes three H-shaped, four-story buildings with apartment-style units for 994 soldiers. The design integrates advanced sustainable systems to reduce energy consumption and enhance occupant comfort.

Key energy-efficient features include:

Radiant heating and cooling with active chilled beams
Heat recovery chiller and 5,000-gallon thermal storage tank
Dedicated outdoor air systems with heat recovery ventilation
Solar thermal panels that meet 30% of domestic hot water demand
Gravity thin-film shower drain heat exchangers
400 kW ground-mounted photovoltaic arrays offsetting 25% of annual energy use
Vacancy and occupancy sensors for lighting control
Automated window sensors and LED lighting throughout

RMH also engineered the adjacent Central Boiler and Chiller Facility (CBCF), which supports the barracks and future development on the Butts Field Plateau. The CBCF includes six condensing boilers, three 400-ton chillers, and over 81,000 feet of hot and chilled water distribution piping.

This project set a new benchmark for sustainable military housing and supports Fort Carson’s transformation into a net-zero energy installation.

BYU-Idaho is Idaho’s largest private University, sitting on a 430-acre campus with a district heating loop providing space heating for 40 buildings. RMH served as mechanical, electrical, and controls engineer for this project to add cogeneration capabilities to the Rexburg campus heating plant. The University replaced its coal-fired boiler plant with a new, multi-leveled heating plant containing a combined heat and power (CHP) system using natural gas. The project began with a conceptual study/economic analysis, which investigated the economic viability of adding cogeneration capabilities.

After completing the conceptual study and economic analysis, RMH designed the installation of a nominal 5.7MWe natural gas turbine with a 50,000 pph HRSG, which has a calculated simple payback of eight years. RMH’s design for the gas turbine featured a fully enclosed evaporative cooling system to increase the turbine output, as well as a turbine enclosure heat reuse system.

The National Center for Atmospheric Research (NCAR) Wyoming Supercomputing Center (NWSC) in Cheyenne represents a significant leap in our understanding of climate, weather, and Earth processes. Designed with a flexible, modular approach, the facility houses next-generation supercomputing systems up to 1,000 watts/SF. It supports researchers in crucial tasks, such as visualizing future climate scenarios and tracking hurricane paths. With a commitment to low energy performance, the NWSC achieves a Power Usage Effectiveness (PUE) of 1.08, positioning it among the top 1% of the most efficient data centers globally.

To capitalize on Cheyenne’s unique cool, dry climate, RMH engineers used evaporative cooling towers to provide sufficient cooling for NCAR’s supercomputing equipment for 96% of the year. A 150′ x 8′ ultra-low-energy fan wall cools air-cooled equipment on the data center floor. Waste heat from the supercomputer is reused to heat administrative areas and melt snow on walkways and loading docks. Additionally, a chilled-beam system delivers efficient cooling in administrative spaces, while ultra-efficient water-saving technologies achieve savings of up to six million gallons annually.

The facility encompasses 153,000 square feet, featuring modular data storage, a visitor center, and a 100,000-square-foot central utility plant. Furthermore, eco-friendly design elements, highlighted by LEED Gold certification, affirm the NWSC’s dedication to environmental stewardship and sustainability. This groundbreaking center advances scientific research and promotes energy efficiency and conservation on a grand scale.

The St. Francis Medical Center in Colorado Springs, Colorado, underwent an expansive project to cater to a 50% increase in patient volume since 2008, aiming to meet the growing community’s needs by expanding its capacity and enhancing care delivery.

The project included the construction of a 250,410-square-foot acute care facility, which features an emergency department, operating rooms, and an upgraded Level III Neonatal Intensive Care Unit (NICU). It also provides additional space for future growth. Key features of the expansion are a 30,000-square-foot parking area, a 34,000-square-foot Emergency Department with adaptable space, two operating theaters, a 22-bay post-anesthesia care unit, and 12,500 square feet for future operating rooms on Level 1. Level 2 has reserved space for surgical expansion, while Level 3 saw a 31,000-square-foot NICU expansion and renovations. Level 4 includes interstitial space for mechanical and electrical infrastructure, and Levels 5 and 6 will accommodate 64 MedSurg beds. RMH also provided the design to update the central utility plant to support the expansion, including a new chiller, boiler, and cooling tower.

The project utilized an Integrated Project Delivery method, completing 56 days early and 2% under budget. RMH introduced innovations such as tunable LED white light technology in the NICU to support infant circadian rhythms, enhancing care quality. Additionally, sustainability and efficiency were emphasized through daylight harvesting and high-efficiency lighting, balancing energy savings with maintaining safe care environments.

The RMH Group delivered comprehensive mechanical, electrical, and plumbing engineering services for the Children’s Hospital North Expansion. This project transformed a 47,000-square-foot clinic into a 236,000-square-foot pediatric hospital, addressing the growing needs of Northern Colorado and Wyoming families.

Key services included HVAC, medical gas, building automation, energy code compliance, and fire protection systems. The project utilized the Integrated Project Delivery (IPD) method, ensuring efficient collaboration and innovation. Notable features include wireless lighting controls and advanced standby power generators, enhancing energy efficiency and reliability. The expansion also added a new medical office building, an outpatient clinic, and critical infrastructure upgrades. This leading-edge facility now offers comprehensive pediatric services, including orthopedics, cancer care, and emergency services.

The collaboration between the project team and the Owner’s staff led to creating a facility that achieved an Energy Use Intensity (EUI) of 150, surpassing the future compliance benchmark of 172 EUI set by the State of Colorado’s Building Performance Standards for hospitals by 2030.

The Lockheed Martin Space Systems Gateway Center at the Waterton Canyon campus marks a significant leap in satellite production capabilities. This $350 million, 266,000-square-foot facility focuses on designing, manufacturing, and testing satellites. Within its expansive layout, 175,000 square feet of SCIF support secure operations for national security missions.

The Gateway Center features a high bay Class 100k clean room, enabling the simultaneous construction and testing of large and small satellites. It also houses a large thermal vacuum chamber that replicates the harsh conditions of space, allowing for rigorous satellite testing prior to launch. Complementing these facilities is a sizable anechoic chamber for safely testing satellite antennas, sensors, and communication systems, as well as a large volume airlock that streams the departure of completed spacecraft in a controlled, clean environment.

The project includes redundant power systems, uninterruptible power supplies, generators, and a central utility plant, achieved through meticulously coordinating highly technical equipment.
